How does the blackbody spectrum of the Sun work compared to visible light? Learn about the blackbody spectrum of the sun, a light bulb, a furnace, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum changes. See the color of the peak of the spectral curve.
The color of a star depends on its surface temperature and can be red, yellow, white, or blue. The higher the temperature, the bluer the star; the lower the temperature, the redder the star. Therefore, by observing the color of the star, its temperature can be deduced.
